Common Name

(-)-kawain

Description

(-)-Kawain, also known as kavain or neuronica, belongs to the class of organic compounds known as kavalactones. These are lactones, which is structurally characterized by a benzene ring and a pyranone moiety, linked to each other to form a 4-methoxy-6-(2-phenylethyl)-2H-pyran-2-one skeleton. (-)-kawain is found in Piper methysticum. (-)-kawain was first documented in 2009 (PMID: 19147309). Based on a literature review a small amount of articles have been published on (-)-Kawain (PMID: 25098935) (PMID: 23227797) (PMID: 22347450) (PMID: 21908763).
